using pin 11 for flow control isn't that strange on a serial printer,
there are several models that do this. pin 18 I have never seen used
on a printer, but 19 is sometimes, and especially with it tied to pin
11 i wonder if the op just miscounted. in any case it sure looks like
a serial printer cable with the flow control mostly looped back..
